According to a rumor released by the well-known insider Tom henderson, a new State of Play in February. The message was the following:
«The current rumor is that the next event of Sony looks like it could be in February. " This speculation is "based on the media events of this month and in the past dates of PlayStation. "
By "past dates" it is possible that he means that there was a State of Play in February 2020, in which Sony introduced Sifu, Final Fantasy 7 Remake: Intergrade and showed trailers for Deathloop y Returnal.
According to Henderson, this possible State of Play it has the potential to be a pretty big one. It is not very clear what he means, but Henderson repeated this last statement when asked about Hogwarts legacy, which could mean that we might see the Harry Potter RPG.
